Top-Rated App Developers San Francisco

Big Human is a full-service technology, design, and branding agency that offers mobile app solutions for San Franscico-based startups, big-name companies, and everyone in between. With experience across all popular platforms and operating systems, our team has a vast skill set that can satisfy any of your mobile app development goals.


Redefining the creative video experience



When you’re hiring a mobile app development company, it’s easy to look to smaller firms if you want to save on costs. Plenty of companies know what it takes to get an app onto the App Store or Google Play store, but there’s usually a difference lies in their ability to anticipate users’ needs and expectations.

At Big Human, we strive to combine our in-depth knowledge of app development with each San Francisco client’s digital needs. We’re a solution-based agency, meaning we start every project with a new client from square one. We don’t bring in assumptions that we’ve taken from past projects. We get to know you first and learn what we can do to solve the problems you’re seeking to address with a mobile app.

San Francisco's Innovative Spirit

San Francisco tech companies quickly learned that mobile app development would become a powerhouse of marketing, sales, and growth in the digital age. After all, the most creative minds are drawn to San Francisco's spirit of innovation — and that includes Big Human. Though based out of New York, Big Human’s team is remote-first — so really, we’re only a quick call away.

Big Human is a team of design, development, and strategy experts that brings creative expertise to all elements of development. In order to build the most seamless app experience possible, we approach development a little differently. Here’s what that means.

What Our Clients Are Saying

App Development for Startups

The Big Human engineering team is here to help guide you from ideation through execution to get your app off the ground. An expertly designed and developed mobile app will help your startup become an industry rising star.

Startup Branding

Big Human’s branding capabilities can help position (or reposition) your brand for both internal teams and your audience. Our designers, strategists, and copywriters will create brand new core brand elements — including positioning statements, messaging guidelines, logos, fonts, colors, patterns, icons, and more — and in the end, you’ll be armed with an expertly defined and designed brand that accurately reflects who your company is.

We think of development as an ally to branding, strategy, design, and content. In other words, all five of these key services we offer are interconnected in a way that means you can’t set a single aspect aside without impacting the others. Our engineering team knows this well, and that’s why thoughts and ideas about branding, business identity, and design come up organically in our client meetings.

We deliver apps that clients trust as a way to grow their business. Whether we’re launching a new payment processing application or upgrading an existing platform, we have the expertise you need. We create design systems, perform maintenance, develop trading platforms, and much more. Look no further than Big Human for the best mobile app development company to service your business in San Francisco.

Every app development company claims to be creative problem solvers, but our knack for problem-solving at Big Human is unmatched. As creative designers and programmers, we’ve designed and developed apps of our own. Subdial, Vine, and HQ Triva were brainstormed, designed, developed, and launched from the Big Human office.

Having your application accessible from any device is key to helping customers and employees be successful in the modern tech era. We know how to create successful mobile applications, no matter the platform.

Our App Development Process

Like everything we do at Big Human, we approach development as an interconnected part of a business. We develop apps because they’re crucial to the other essential aspects of a modern company. When it’s time to get started with a new app, Big Human is eager to have conversations that excite, inspire, and connect our clients to our mobile app development approach.

Strategy & Discovery

Understanding the business needs of our clients and the user journey of our end users is vital to creating a successful app. Working with clients to dive into their business, along with user research and competitive analysis, allows us to create solutions-first mobile app designs.

Design & Refine

During this phase of the development process we build out design concepts and wireframes to organize the features of the mobile application. Our goal is to create an eye-catching, seamless mobile experience.

Develop & Test

Our developers are well-versed in different languages and platforms and can build custom mobile app development solutions based on the needs of each San Francisco organization. Big Human’s development philosophies center around one thing: developing for real people with real needs. That said, our solutions always guide users to access products across all platforms and operating systems.

Launch & Iterate

We love the feeling of launching a new mobile app for our clients, but our job doesn’t end once the product is live and in the app store. We work with San Francisco clients at every step of the custom app development process. This includes ensuring the product functions seamlessly, that users can successfully navigate it with ease, and that asset handoff will be a smooth process.

Our App Development Work

A mobile app can be a monumental step for your business. Whether it’s the first app a brand is launching or a revamp of an old experience that wasn’t working, we take app development clients in San Francisco and set them up for success. It serves our clients well, and it helps us remember why we do what we do: There’s a solution out there to everything, and we’re here to help find it.
